福建CAMERA BRACKET

The powerful function of mobile phone is partly reflected in the camera function, which can replace the camera. You can take beautiful pictures with your hands, and the operation is very simple. On the contrary, the easier it is to operate, the more high-tech it is. There are many complex precision parts hidden in the mobile phone camera, such as lens, sensor, LED flash, etc. These parts are assembled on the camera bracket.

The design of the camera bracket needs to pay attention to the comprehensive functions and the customer's experience. The experience is embodied in "getting thinner", "getting lighter" and "getting more convenient". Therefore, the camera bracket must pay attention to the requirements of wall thickness, flatness, contour, etc. The existing process of MIM powder injection molding can achieve this effect.

The camera bracket belongs to a complex structural part with a stacking structure, while MIM powder injection molding can realize one-time molding, eliminate machining, mass production, increase the utilization rate of materials and other advantages when producing complex structural parts with a stacking structure.

Advantages of MIM in manufacturing mobile phone parts:

1. High efficiency, good at mass production of batch parts

MIM technology uses molds. Because of the high degree of production automation, its service life is equivalent to that of engineering plastic injection molding tools. Because of the use of metal dies, MIM is suitable for mass production of parts.

2. More refined parts

Alloying has good flexibility, wide application range of materials, the density of products reaches 95% - 99%, the internal organization is uniform, without internal stress and segregation, the surface finish is good, the precision is high, and the typical tolerance is ± 0.05mm.

3. Substantial energy and material conservation

MIM can use almost all metal materials. Considering the economy, the main application materials include iron based, nickel based, copper based, titanium based metals or alloys. Generally, the utilization rate of metal processing and molding is relatively low. For example, the utilization rate of raw materials for the metal shell of LeTV MAX mobile phone is less than 10%, and most of the aluminum alloys become debris. MIM can greatly improve the utilization rate of raw materials, which is 100% theoretically.

4. Structural parts with highly complex structure can be formed

Generally, the tolerance accuracy of ± 0.5% can be achieved with MIM, and higher dimensional accuracy can be achieved with other processing methods. Basically, all structures that can be realized by injection mold can be applied to MIM.

5. Environmental protection and safety

It is pollution-free and can realize continuous mass clean production. It is a near net forming technology and can effectively avoid material waste.

6. More material choices

Most metal materials can be used in MIM. In consideration of economy, the main application materials include iron base, nickel base, low alloy, copper base, high-speed steel, stainless steel, gram valve alloy, hard alloy and titanium base metal.
